I guess that's because I don't know what a DIN 41419 is, and don't know what size a "Eurocard" is, nor why that would be a desirable size. The board is basically built around the prototype area. I'm currently thinking the board will be about 6" wide, which accomodates the 50 prototype columns with room for rubber feet or mounting holes. Extra connector pads could fit in the extra width not used up by the mounting. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
